Eligibility Criteria of Participants in Randomized Controlled Trials Assessing Conservative Management of Cervical Radiculopathy: A Systematic Review.

Overall, there is still a lack of uniformity for the inclusion/exclusion criteria of trials assessing the conservative management of CR, with some improvements noted compared to the 2012 review. Based on the current literature assessing the diagnostic utility of clinical symptoms and confirmatory tests, we proposed inclusion criteria for trials assessing conservative interventions. Future research should aim to develop standardized classification criteria in order to improve consistency among studies.
